All atoms of an element always have the same number of question 4 options: electrons protons electrons neutrons save

All atoms of an element always have the same number of protons (the positively charged subatomic particle).

Isotopes of the element differ in the mass which means that they differ in the number of the neutrons (which are the subatomic particles having no charge).

At neutral state only will the number of protons be equal to the number of electrons in an atom.

The given information gives us the clue that deuterium and tritium react together. We need to find the balanced nuclear reaction of deuterium and tritium; however, first, let me explain you what deuterium and tritium are.

Deuterium and tritium are two isotopes of hydrogen having atomic mass of 2 and 3 respectively. Deuterium is represented by , whereas tritium is written as .

When deuterium and tritium collide together, they form Helium atom, which is written as , and also release energy (and shoot out one neutron).

Hence, the balanced nuclear reaction will be the following:
